When are we required to keep a more-than-customary distance from the vehicle driving in front of us?
- When driving in low speed on an urban road.
- When trucks or other heavy vehicles are in front of us.
- Never: A distance of two seconds is always sufficient.
- Correct answer: When visibility is poor, when driving on a slippery road or when we are tired.
Why this is the answer
The correct answer in the official bank: When visibility is poor, when driving on a slippery road or when we are tired.
A two-second gap only suits normal conditions. In poor visibility you spot hazards later, on a slippery road braking distance grows, and when you are tired your reaction time is slower. In all these cases you need extra time and space to stop safely, so the gap to the vehicle ahead must be increased beyond the usual.
